Evidence of Third Dredge-up in Post-AGB Stars in Galactic Globular Clusters
The Astrophysical JournalTo better understand the mixing and mass loss experienced by low-mass stars as they ascend the asymptotic giant branch (AGB), I have gathered from the literature the abundances of CNO and s -process elements in post-AGB stars in Galactic globular ...

Walking With Dragons: Performance, the Sensorial, and Urban Change in Vancouver, Canada
City &Society, EarlyView.ABSTRACT This article discusses the “Dragon Walk” project, a series of guided walks and participatory art‐based community gatherings purposefully located in one of Vancouver's major redevelopment landscapes, the Cambie Corridor. Adopting a “cats' cradle” approach to thinking and writing, I follow Dragon Walk's suggestion that we look at urban change ...

Downlisting and recovery of species assessed by the IUCN
Conservation Biology, EarlyView.Abstract Despite the increasing number of species assessed for extinction risk by the International Union for Conservation of Nature (IUCN) (163,040 species as of 2024), only about 1 in 1,000 have been downlisted due to genuine population improvement. Although this rare conservation achievement has been widely celebrated in several recent cases, some ...

Cell Proliferation, EarlyView.Maternal nutrient restriction disrupts placental homeostasis via GAB1 dysregulation—involving both transcriptional downregulation and autophagy‐dependent protein degradation. These molecular alterations inhibit MAPK signalling‐mediated trophoblast fusion, leading to structural and functional deficits in the maternal–fetal exchange interface.
